On May 1, 2019, a protester tossed a milkshake at far-right activist Tommy Robinson on a sidewalk in Bury, England7. The following day, a man named Danyaal Mahmud dumped a McDonald's milkshake over Robinson's head during a confrontation in Warrington1. The Observer tracked Mahmud down and described him as an "everyday hero"1. Both milkshakes were reportedly strawberry. Robinson responded to the second incident by punching the thrower8.

The trend drew inspiration from the "Egg Boy" incident in March 2019, when Australian teenager Will Connolly smashed an egg on the head of far-right senator Fraser Anning3. Egging went viral and showed how food-based protest could make a right-wing figure look foolish on camera. But milkshaking took the concept further. As the Daily Dot put it, "for whatever reason, milkshaking took off in a way egging didn't"3.

Milkshaking broke through into mainstream political discourse in a way few protest tactics do. It was debated by former prime ministers, analyzed by university philosophers, and covered by publications from The Financial Times to The Atlantic13. Major brands waded into the conversation, with Burger King's tweet becoming a viral marketing case study.

The practice forced real operational changes. Police asked fast-food restaurants to halt milkshake sales during political events, which only amplified media coverage and public amusement1. The cement milkshake hoax spawned its own media literacy discussion, studied as a case of how falsehoods get laundered through official channels and amplified by partisan outlets4.

Milkshaking also became a fundraising engine for both sides. Supporters of the milkshakers set up JustGiving pages and organized events1. Supporters of the targets raised hundreds of thousands of dollars through GoFundMe campaigns3.

Political scientists and philosophers quickly placed milkshaking in context. Dr. Ivan Gololobov, a politics teaching fellow at the University of Bath, called it "an incredibly powerful image destroying the platform of seriousness for the likes of Robinson and Benjamin"1. The drink's association with childhood innocence created a pointed contrast when splattered across politicians in suits. "Who drinks milkshake? Kids and teenagers," Gololobov said. "Milkshake on a fancy suit of an upper middle-class bigot symbolises how fake their bravado is and how irrational their arguments are"1.

There was a symbolic dimension too. The alt-right had adopted milk as a white supremacy symbol, referencing its color and mocking people with lactose intolerance1. Dr. Franks argued the milkshake flipped this on its head: "The milkshake is turning that symbol against them. It is an example of political ju-jitsu. It also makes them look foolish, undermining their self-image of power and control"1.

The ethical debate was sharp and immediate. Comedian Ricky Gervais pushed back against supporters, calling it hypocritical that people who considered certain speech harmful didn't view milkshaking the same way3. The Guardian argued milkshaking was political theater rather than violence, while The Atlantic wrote that "Sometimes a milkshake is just a milkshake"3. Leftist labor writer Kim Kelly published her "perfect" recipe for an anti-fascist milkshake, a detail that showed how deeply the practice had embedded itself in protest culture3.

The Portland incident on June 29 changed the conversation. After Ngo's assault, Portland Police tweeted they had "received information that some of the milkshakes thrown today during the demonstration contained quick-drying cement"4. Conservative commentators including Jack Posobiec ran with the claim3. Misleading photos purporting to show concrete burns turned out to be stock photos and fabrications3.

The story collapsed under scrutiny. Willamette Week reporter Katie Shepherd found that police had zero physical evidence of cement in any milkshake4. The tweet had originated after a single officer thought he spotted something on a cup, and an anonymous email claiming a "Quick Rete Cement Mix" recipe was sent to the department afterward4. Conservative media had already pushed the narrative far beyond what any evidence supported3. Ben Decker of the media investigations consultancy Memetica called it a calculated effort to "gaslight and attack Antifa," noting that negative posts about Antifa "make it easier to find negative information about Antifa, true or not"4. Fox News initially reported the cement claims as fact, then quietly rewrote its headline and article4.

The legal aftermath was real on both sides. Farage's milkshaker pleaded guilty to common assault and criminal damage, receiving 150 hours of unpaid work and a £520 fine8. A GoFundMe set up by conservative commentator Michelle Malkin for Andy Ngo's medical expenses raised nearly $200,0003.

Milkshaking went quiet for several years before its biggest revival in June 2024. Farage was hit with a McDonald's banana milkshake while campaigning for Reform UK in Clacton by a 25-year-old woman named Victoria6. The incident generated a fresh wave of memes, including a video looping high-resolution photos of the impact set to "Milkshake" by Kelis6. Others dropped the moment into the George W. Bush 9/11 whisper format. Farage leaned into it, posing with his own McDonald's milkshake on social media hours later.
